At the prompt, enter the baud setting for the Console

19200, 9600, 4800, 2400, and 1200.

The system changes the settings and displays this 
message:

Changing the baud rate may cause a loss of 

communication since you are currently connected

 (for yes) or 

 (for no) at the prompt.

If you enter

These instructions include information on how to 
define an IP interface through which you can manage 
your Switch 3900 system. An IP interface contains the 
following parameters:

■

IP address — This address, which is specific to 
your network, is used to manage the system. The 
IP address defines both the number of the network 
to which the interface is attached and its host 
number on that network.

■

Subnet mask — This 32-bit number uses the 
same format and representation as an IP address. 
The subnet mask determines which bits in the IP 
address are interpreted as the network number, as 
the subnet number, and as the host number. Each 
IP address bit that corresponds to a 1 in the subnet 
mask is in the network and subnet part of the 
address. Each IP address bit that corresponds to a 0 
is in the host part of the IP address.

To set the IP interface parameters: 

From the top level of the Administration Console, 
enter:

Enter the IP address of the interface.

Enter the subnetwork mask of the subnet to which 
the interface is to be connected.

Enter the interface type as 

.

parameters, see the SuperStack II Switch 3900 and 
9300 Administration Guide.
